Premium subscribers must go online with Spotify at least once every 30 days. This is so Spotify can check your subscription is still active and count track plays to compensate artists.

If you don’t go online with Spotify at least once every 30 days, any tracks you’ve downloaded for offline listening are automatically removed from your device.

You can download Spotify tracks for offline listening on up to 5 devices at a time.

If you want to download music to a 6th device, you have these options:

When you download to the additional device, the device with the earliest downloads is automatically removed from the Offline devices list. The tracks on this device will no longer be downloaded for offline listening.

Before you download to the additional device, manually remove a device from the Offline devices list. The tracks on this device will no longer be downloaded for offline listening.
